Ciaims priority, application Switzerland January 31, 1953 6 Claims. (Cl. 139294) The present invention relates to a temple for looms with two sets adapted to engage the fabric on each side and having, supported by an open end slot of a holder with slot surfaces converging toward the opening, a roller which is spring-biased toward the slot opening, said holder being disposed so as to form an acute angle with the fabric in the direction of movement, thus engaging the latter in the region of its selvedge near the reed and holding the fabric, when stationary, friction-tight by spring pressure between one slot surface and the roller, and disengaging itself automatically upon feed of the fabric.

The temple according to the invention is characterized by its simple design, easy mounting and dismounting as well as by little wear and tear. The temple makes it possible to safely hold the selvedge in closest proximity to the reed and causes neither damage to the fabric nor distortion of the weft and warp threads. It requires no 111- brication and can consequently leave no oil spots whatever in the cloth. It allows the cloth to be quickly disengaged from the holder without having to alter the position of the latter, thus making it possible at any time to inspect a small part of fabric underside and to remove without ditiiculty any faulty wefts. On throw of the reed the selvedges become automatically re-engagcd.

The accompanying drawing shows by way of example a preferred embodiment of the invention.

Fig. l is a top view of the temple set on one side of the fabric;

Fig. 2 is a lateral view in the direction of the arrow A in Fig. l, and

Fig. 3 shows the holder as seen from its working end.

The temple comprises two similar sets arranged one on each side of the fabric, of which sets only one is shown in the drawing.

The set illustrated includes a holder 1 secured at its rear end to a support 2 by means of a screw 3. The holder It is adjustable on support 2 and has for this purpose several holes 4, while the support is correspondingly provided with several threaded holes 5. The possibility of having the holes 4 coaxially registered with the threaded holes 5 for the purpose of connecting them by the screw 3 permits the holder to be set at any desired angle to the running direction B of the fabric and at any distance of the reed from the beam 7 of the loom. At its thickened rear portion the support 2 has a bearing slot 8 through which it rests on the beam 7, being clamped thereto by a screw 9 inserted from the back into the support. in this way the support 2 can be mounted on and dismounted from the holder 1 without taking away the beam. The working extremity or face of the holder 1 has an open ended slot 10, the upper and lower surfaces thereof converging toward the opening. In the embodiment shown the lower surface of the slot extends horizontally, the upper surface being inclined thereto at an acute angle so that the slot is tapering toward the front of the holder 1. Supported by the slot 10 is a roller 11, the length of which corresponds to the width of the holder States Patent 0 2,730,139 Patented Jan. 10, 1956 and whose diameter is larger than the slot. The roller 11 is urged toward the opening of slot 10 by means of two compression springs 12 located and secured therein. Numeral 13 designates a guard, U-shaped in cross-section, having a flap 13a which covers the end. Said guard 13 can be swivelled and raised about pivot studs 14 in order to remove the roller laterally. With guard 13 lowered the roller 11 is guided by the side portions thereof. At its lower edge the front flap 13a is provided with a recess 15 through which the roller may easily be pushed into the slot, say by means of a small wooden stick.

On support 2 the holder 1 is disposed at an angle of about 50 degrees with respect to the running direction B of the fabric. Thereby the position of the support 2 on the beam 7 is chosen in such a way that the fabric 16 with its selvedge 16a in the slot 10 will pass through be tween the roller 11 and the lower surface of the slot and becomes loaded, obliquely inwards from the selvedge 16a, by the spring-biased roller 11. The roller 11 preferably engages the selvedge as near as possible to the reed 6, say at a distance a of about 3 mm. /8), and holds the fabric for a length b of about 15 mm. under a spring (12) pressure of about grams. At each feeding movement of the cloth the roller, set at an angle to the feeding direction, will move slightly backwards till clamping is released. A biasing of the selvedge, opposed to the holding out of the cloth, such as tends to occur at each weft, Will be prevented by the roller clamping the fabric in the narrowing of the slot. By pushing the roller 11 inwards, say, by means of a wooden stick, its pressure will be relieved and the fabric disengaged so that it can be taken out of the holder. This makes it easy to examine a small part of the fabric underside, which is often necessary in particular when changing the pattern. When the fabric is taken out of the holder, the latter maintains its position. When the reed next moves, the selvedge will automatically be again pushed into the holder and under the roller 11 and its position secured, thereby preventing the fabric from slipping back which would cause a reduction in width of same.

The angle of the holder with respect to the movement of the fabric is determined when working the latter in, and differs according to the type of the woven material.

With fabrics, for which a course weft material is usedthe cloth then being produced 1 mm. thick and more-the roller 11 may be exchanged for a correspondingly smaller one, for which purpose the guard 13 need only be raised.

Various changes and modifications may be made without departing from the spirit and scope of the present invention and it is intended that such obvious changes and modifications be embraced by the annexed claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

l. A temple for a loom having a beam; said temple comprising a pair of spaced sets for engaging the selvedges of a fabric, respectively, each of said sets including a holder operatively connected with said beam and forming an acute angle with the fabric in moving direction of the latter, each of said holders being provided with a slot having converging slot surfaces defining a slot opening, roller means disposed within each of said slots, and spring means urging each of said roller means toward its respective opening, whereby when said fabric is stationary said selvedges are held friction-tight between said rollers and said slots, respectively, said selvedges automatically disengaging said rollers upon feed of the fabric.

2. In a temple according to claim 1, including support means for each of said holders, and means for clamping said support means to said beam, said support means being adjustably connected with said holders, respectively, whereby the angle formed between said holders and the fabric may be adjusted.
